`To all whom 'it may concern :v

B'e it known that;I,'S.,L. BIGNALL, of Chicago, in

thecounty of Cook,` and State of Illinois, have invented a. new and useful Improvement in Tube-Wells; andI do hereby declare that Athe'following is a full, clear, and'exact description-thereof; reference being had to the accompanyingdrawings, and letters marked thereon, making a part of this description, in which- Figure l is a perspective representation of my im proved well-point.

Figure 2, a central section of the same. Figure 3, a perspective view of. one wing of the sinking'and packing-device removed from the point.

Figure 4, the ring to'which the wire cloth is attacbed.v 1

Figure 5, the wirecloth before it is formed over the Figure-6, Viewlof-the-jwire. cloth as it is formed over the ring,- prep atry to being soldered to the tube. A f v Fig-ure 7, a top 'view of one of. the wings.,

The nature of thepresentrinvention consists- First, in` thefnovel Construction ofuthe device for removing-the earth as' the tube is being put down, and

so packing it as to inake'av hole somewhat larger than thetube, thereby 'allowing' the latter to be sunk to a great1 deptjh by hand-power, in any'soil'where there are no stones. i

Secondly, in forming the wire cloth, used for screening-purposes, o ver rings, which are so' bent as to fit the periphery of the pipe to which they are soldered.

A represents the lower end of an ordinary pipe used in sinkingitube-wells, and J J, Snc., show the holes through which the -water passes into it.

vG represents a metal screw-point, which is placed inside ofthe tube A, and fastened there by means of a bolt or otherwise, as most convenient.

It is not necessary, however, for sinking wells in sandy'soil, that the point' G should have a screw.- thread, a plain conical point 'heilig suiiicient to guide the tube'. l v

Wings, O, made of steel or iron, according to the servicereguired, are bolted fast to the point G," between the screW-threadand a shouldei-,IQ the opposite sides of the point being iiattened or cut away for this. purpose.

These wings extend out a shortdistance beyond the periphery of the tubeA, and are provided with shovel-shaped lips E, on their lower edges, for loosening the soil as the tube is being sunk, and with anges l) on their outer ends, for the purpose of so packing the earth surrounding the h ole, as it is loosened, as to forln awall sufficiently compact to relieve the tube A from any lconsiderable friction, which would other- .wiseresult if the earth were permitted to fall back against it.` .In-manufacturing the points, it is not necessary that the'wings should be bolted to the screw-point G,

as the whole can be readily cast in the proper form, Y

of malleable iron.

There may be instances, however, in which the na# ture of the earth may require -a steel point through out.

In any case, the lips E should have a pitch of about sixty degrees, and the flanges D inclined loutward a' little from the wings C, as shown at iig. 7.

By means of a point thus constructed, a tube-well can be sunk to a much greater depth than 'when drivf! ing is wholly relied on, and at much less cost thanwhen the earth is` carried to the surface with an au ger, saving, at the same time, the expense of a`driv ing or boring-machine, and valso the trouble of moving 5 r one from place to place.

The holes J .J Irc., are covered with wire cloth, asv

follows:

A series of wire rings, M, iig. 4, co1respondingto the number of vholes J through the tube A, is 'so covered with circular pieces of wire cloth,f1, as to pro#- V ject above the area of the enclosedv parts through lwhich the water passes. I

'This is generally done with dies made for the pur-fpieces I, may be quickly formed over the rings by hand, care-being taken, however, not to 'out the pieces of wire cloth so pose, but the edges ot the circular large as to more than overlap the rings The rings, with the cloth on, are then so formedperiphery of the tube (surrounding the holes J .J &c.,) to whieh'xby a die or otherwise, as `closely to lit `the they are fastened with solder pn-t around the outside,

By means of this arrangement, the wire cloth held much more firmly in place than when simply secured by soldei alone, while, at vthe same time, the -ad#v .ditional costof rings' is saved in solden The operation is very simple, requiring only thatthe .tube-A have a length of pipe screwed fast to it, and turned into the earth by ordinary T-couplings, in

.the usual manuel', or other means now used for alike purpose, other lengths 0l' pipe heilig fastened to the preceding ones, until water is reached.

It' the screens fill up, the whole tubing can beliited out of the. earth, where the well is of moderate depth, but if it is very deep, the tubing may have to be ro-v tated when being hoisted o ut.

Having thus fully described my invention,

That I claim, and desire to secure by Letters Pat-` ent of the'United States, is- Y A tube-well, A, provided witha point, G, and wings (l, said wings being provided with lips E, for loosening the earth, and withiiangesl), for packing the walls of the hole, as set forth. S. vL.-BI( JrNALL.
